If you liked the guidance on the Cruiser, and you already have the accuboom node & Raven product control components, and plan to install smartrax, I believe your cheapest (and best) option would be to stay Raven. Envizio in my opinion has a more advanced guidance package than Viper, (esp in last pass mode) and is a little more self explanatory to setup. The Viper has a bigger display, can connect a weather station, and has some more advanced reporting, like enter data in the application report from the display, etc.
